Gibraltar GIB53629 Round U-bolt with Mount Plate 1 Inch Pipe

Product Description

The GIBRALTAR GIB53629 is a round U-bolt with a mount plate designed to secure 1-inch pipe to structural surfaces in mechanical, plumbing, and HVAC piping systems. Manufactured from C-1010 steel with a hot galvanized finish, this fastener resists corrosion in exposed or wet service environments. The 1/4-20 UNC thread standard ensures compatibility with standard hardware. Thread length is 1.375 inches, and two nuts are included for immediate installation without additional fastener sourcing. Licensed plumbers, pipefitters, and HVAC mechanics commonly use this style of U-bolt when strapping pipe runs to unistrut, beams, or mounting surfaces.

This U-bolt is suited for securing 1-inch nominal pipe in residential and light commercial mechanical installations. Typical applications include strapping copper, iron, or PVC pipe runs along walls, ceilings, or framing. The mount plate design provides a flat bearing surface that distributes clamping load and simplifies attachment to flat substrates. It is a standard component in pipe support assemblies used by plumbing and HVAC contractors during rough-in and retrofit work.

Installation Notes

Install by a licensed plumber, pipefitter, or HVAC mechanic in accordance with applicable IPC or IFGC pipe support spacing requirements. De-pressurize and isolate the pipe run before final positioning and tightening. Use appropriately sized hardware anchors rated for the substrate when mounting to concrete, masonry, or steel framing. Do not overtighten the U-bolt nuts against plastic pipe without using a protective liner or sleeve.
